Sea Surface Temperature Affects the Reproductive Biology of Female Pearl Perch (Glaucosoma scapulare Macleay, 1881) in Queensland, Australia

Figure 6

(a) Length-at-maturity (mm fork length) and (b) age-at-maturity (years) for 281 female Glaucosoma scapulare caught in southern Queensland. Dashed lines represent 95% confidence intervals. Hollow diamonds represent the observed data, where 0 = immature and 1 = mature. The red point represents the length at which 50% of females are mature (t₅₀, L₅₀) and the blue point represents the length at which 95% of females are mature (t₉₅, L₉₅). Horizontal error bars represent the 95% confidence intervals of the respective point estimates.
